| Contactless voltage regulator
|
The AVR contactless AC voltage regulator is a stable voltage source that uses the ARM new generation 32 bit processor as the core, SCR as the actuating component and the compensation transformer as the voltage compensation mode.
It mainly solves the voltage problems such as large voltage fluctuation, unbalanced three-phase voltage and load voltage drop frequently。
Optional isolation transformer, LC filter, ATS dual power input, SPD lightning protection module, multi channel power distribution. |
